This is Twinkle Twinkle Little Star: 24 | this sets default note to a 2^2 quarter note
24 c c g g a a 1g f f e e d d 1c g g f f e e 1d g g f f e e 1d c c g g a a 1g f f e e d d 1c
now , just replace all g's with 9's and you have hex. The 1's are 1/2^1 = 1/2 notes
I have an example of minuet played in HexNoteG9 as well as more details on the modifiers, how to do rests, octaves, sharps, flats, dotted half notes, dynamics, looping, and comments: https://drive.google.com/file/d/1atnHKK4mbMjGrJFFhCk76e9YaTAkiv5y/view?usp=sharing
I want to make a specification that is peer reviewed similar to how the JSON specification looks https://tools.ietf.org/html/rfc7159
My end goal is to standardize a specification so that other people can adopt and use it. It would be nice to build tools off of this with other people.
